Question

Classify these reactions as endo or exothermic?

Answer 1

@abb0t @chmvijay @aaronq can you help me?

Answer 2

I know that stronger reactants and weaker products mean it is endothermic.

Answer 3

Well, you should know the basic ones, for instance, making a bond requires energy, while breaking bonds releases. Do you follow me.

Answer 4

Yes.

Answer 5

So, that should help you with about 50% of those.

Answer 6

Let me be sure I do. For example, A2+B2--->2AB. It has a strong bond strength, right? and It yields a strong bond?

Answer 7

Yes, therefore it may be safe to assume that it requires much energy.

Answer 8

Ok. Thanks.

Answer 9

Well, I guess I just don't get it. Sorry I said I thought I did. I have missed it 3 times.

Answer 10

Lol.

Answer 11

I want my mommy. Can you help straighten this out?

Answer 12

Find \(\Delta\)H for your bonds.

Answer 13

Delta H? Change in enthalpy? Um...ok.

Answer 14

Its all letters?
